How V8 Engines Work - A Simple Explanation

General Motors' 3. This engine has been the forerunner to the manufacture of the Cadillac Northstar 4. With a block made of metal cast iron, this 6 cylinder engine has 3 cylinders on each side arranged in a V shape. The right bank cylinders 1, 3, 5 are on the cowl end of the engine section whilst the left bank cylinders 2, 4, 6, are located on the front side of the car.

The crankshaft, which is retained by bearing caps that are machined with the block for proper alignment and clearances, is held in place by four bearings. The aluminum cylinder heads have two intake and two exhaust valves for each cylinder. These heads contain pressed-in valve guides and valve seat inserts.

The aluminum camshaft carriers each contain one intake and one exhaust camshaft. The aluminium in the carrier serves as the camshaft bearing surface. The camshaft thrust plates, which control the camshaft location, are mounted on the rear of the carriers. The camshaft drive is a bi-stage system.

Initially, it transfers power from the crankshaft to an intermediate shaft via a chain drive. The second stage uses a belt between the intermediate shaft and the individual camshafts. Both chain and belt tension is set and maintained by fully automatic tensioners. Timing must be reset if sprockets are removed from their shafts.

Pins or keys are not used to establish camshaft to crankshaft timing in this engine. The GM3. The piston pin is offset 0. This permits a gradual change in the thrust pressure on the cylinder wall as the piston moves in its path. Pins are chromium steel and have a floating fit in the pistons. They are kept in the connecting rods by a press fit. Connecting rods are made of forged steel. Full pressure oiling is channelled to the connecting rods by drilled oil routes from the adjacent main bearing journal.

These engines vary in displacement between 2. Production of these engines began in and ended in in the U. This engine family was the basis for the GM High Value engine family. These engines have also been referred to as the X engines due to their first usage in the X-body cars. This engine is not related to the GMC V6 engine that was designed for commercial vehicle usage.

This "clean sheet" design was introduced in and versions were produced through Two different blocks with minor differences were developed:. Like the rest of the Generation I engines, they were updated in with larger main journals for durability, along with multi-point fuel injection or E2SE carb and OBD I.

Production of the Generation I transverse engines ended in The 2. It was a transverse version produced from through for the A-body and X-body cars. The standard "X-code" engine for this line, it used a two-barrel carburetor. Introduced inthe 2. The L44 was produced from toreplacing the LH7.

It was the first transverse 2. The LB6 engine was introduced in to replace the original LE2. The LG6 "D-code" was produced from to in both transverse and longitudinal applications. It used throttle-body fuel injection and iron heads. The longitudinal versions had minor differences from the transverse engines on which they were based. Like the rest of the family, larger journals appeared inalong with multiport fuel injection for the F-body LB8 version. TBI was added for the truck version in Production of the 2.

GM's performance-parts division continued production of a related crate engine after The longitudinal LC1 was produced from to It was a 2-barrel High Output "1-code" version for the F-body cars.

It was replaced by the LB8 for The longitudinal LR2 was a truck version "B-code" produced from to The longitudinal LL1 was a high-output version of the LC1 produced in and It was used in the — Pontiac Firebird.

The carbureted LL2 "R-code" was produced from to Another LL2 "R-code" with throttle-body fuel injection was produced from to It used multiport fuel injection and was made for longitudinal mounting. The LH0 as used in the rear-wheel drive applications differed significantly from that used in front-wheel drive applications.

The latter retained the generation-I architecture block and heads. The power rating of the 3. The F-body cars used the Generation I architecture, with iron heads, and without splayed valves. The second generation, still 2. It used aluminum heads with splayed valves and an aluminum front cover.All you need is a multimeter and this article will take you step by step thru' the whole process. Although a scan tool is a great tool to have and you should have oneit's not needed for the test in this article.

The test that I'm going to show you is a dynamic test done by hand cranking the engine. The camshaft position sensor can not be tested by doing a simple resistance test in Ohm's mode on your multimeter. The way this article is presented, is that you jump right into the test but I recommend that you first take a look at the section entitled: How the CMP sensor Works.

Think safety and use common sense. Never trust the jack alone to hold up the vehicle! The most obvious symptom of a bad cam position sensor is the check engine light, on your 3. When the camshaft position sensor fails, it usually doesn't keep the car from starting.

In other words, in the majority of the cases the car starts and runs although it won't run like a champ. There's a good chance that you can buy the original AC Delco Delphi camshaft position sensor online for a whole lot cheaper than somewhere local. The following links will help you comparison shop for the factory original AC Delco and aftermarket camshaft position sensor:. Unsure if the above camshaft position sensor fits your particular vehicle?

Don't worry, once you get to the site, they'll make sure it is by asking you the specifics of your vehicle. If the above don't fit, they'll find you the right one. The three wire camshaft position sensor, on your 3. In this article, I'm gonna' show you how to test the cam sensor and thus code P with a multimeter. The most important thing to know, is that the CMP sensor will not keep the car or mini-van from starting if it goes bad, although once started, it won't run right and will set a diagnostic trouble code DTC P I like the whooshing sound they make as they fly by.

This provides optimal performance, fuel economy, and control of exhaust emissions. This ignition system uses one coil for each pair of cylinders. Each pair of cylinders that are at top dead center TDC at the same time are known as companion cylinders. The cylinder that is at TDC of the compression stroke is called the event cylinder.

The cylinder that is at TDC of the exhaust stroke is called the waste cylinder. When the coil is triggered both companion cylinder spark plugs fire at the same time, completing a series circuit. Because the lower pressure inside the waste cylinder offers very little resistance, the event cylinder uses most of the available voltage to produce a very high energy spark.

This is known as waste spark ignition. The EI system consists of the following components:. The CKP sensor B is a variable reluctance sensor.

The magnetic field of the sensor is altered by a crankshaft mounted reluctor wheel that has seven machined slots, six of which are equally spaced 60 degrees apart. The seventh slot is spaced 10 degrees after one of the 60 degree slots. This sensor provides the ignition control module ICM with 7X signals, or seven pulses for each revolution of the crankshaft.

The pulse from the 10 degree slot is known as the sync pulse. Both of the sensor circuits are connected to the ignition control module ICM. A signal converter within the ICM produces digital 3X output pulse to the powertrain control module PCMthe 3X reference is known as the low resolution engine speed signal.

The CKP sensor A contains a hall-effect switch. This rotating element is called an interrupter ring or blade. In this case the interrupter ring has 24 evenly spaced blades and windows and is part of the crankshaft damper assembly.On Sale.

OK i've been trying for the last hour to install this freaking sensor on my The crank pulley should just tap off with a mallet, it is not pressed on.

To get the harmonic balancer off however you will need a puller tool. You may be able to borrow the tool from a parts store. Zahn CTS-4 3. Originally Posted by judge. Torque what? The only thing I worry about torquing to spec is shit like head bolts. Those 5 bolts only hold on the crank pulley, the balancer ain't going anywhere.

I put my underdrive pullies on and had the front cover off twice and never torqued those to any spec, just crank 'em down. I'm sure someone will scream bloody murder like I've just said something sacrilegious, but I don't even own a torque wrench and they're too damn expensive for a good one so I just borrow one when I need it for the critical stuff.

Yeah, the center bolt must come off for the harmonic balancer and crank pulley to come off. Go to Autozone and get a harmonic balancer install tool also. Get it on the Loan-A-Tool program so that you can take it back and get your money back.
